drse opened a new issue, #3674: URL: https://github.com/apache/fory/issues/3674
### Search before asking - [x] I had searched in the [issues](https://github.com/apache/fory/issues) and found no similar issues. ### Version Fory version: 0.17.0 ### Component(s) Java ### Minimal reproduce step ```java @Value.Immutable interface Price {} record Order(int id, Price price) {} // Fory COMPATIBLE mode: // 1. Order is serialized; Price enters META_SHARE // 2. Fory JIT-compiles codec for Price // 3. On deserialization: Unsafe.allocateInstance(Price.class) → InstantiationException ``` ### What did you expect to see? Fory should detect that a META_SHARE type is an interface (or abstract class) and either: - Not JIT-compile an instantiating codec for it, or - Use the concrete runtime type from `TypeResolver` for allocation ### What did you see instead? When the type graph of a serialized payload includes a field declared as an interface type, Fory adds that interface to the META_SHARE type table and JIT-compiles a codec for it. During deserialization the JIT codec calls `Unsafe.allocateInstance(InterfaceClass)`, which throws `InstantiationException` — interfaces cannot be instantiated. ### Anything Else? I'm running into this issue when using [Immutables.org](https://immutables.github.io/) annotated interfaces. ### Are you willing to submit a PR? - [ ] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
